Description
RELATED APPLICATIONS
[0001] This application is a continuation of pending International
Application PCT/EP01/10091 filed on Sep. 1, 2001 which designates
the U.S. and which claims priority from German Utility Model
Application 200 17 320.0 filed Oct. 6, 2000 both of which
applications are incorporated herein in their entireties by
reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to an awning having a sleeve which
encloses an awning-canvas shaft, in which the awning canvas can be
retracted and extended through a slit-like opening in the sleeve,
having stationary support means for the sleeve, the lateral holders
thereof retaining the sleeve, and having an arrangement for
adjusting the inclination of the sleeve by rotation of the same
about the awning-canvas-shaft axis.
[0004] 2. Description of the Related Art
[0005] In the case of such known awnings, the awning-canvas shaft
is encased by a sleeve which encloses it. With the awning
retracted, the awning canvas is thus protected against external
environmental influences.
[0006] The awning canvas is extended and retracted again through
the slit-like opening.
[0007] It is often desirable for the awning canvas to be extended
out of the sleeve not horizontally but usually in a downwardly
inclined manner in the direction of gravitational force, for
example, at an angle of inclination of 30.degree., 40.degree.,
50.degree. or more, depending on the customer's wishes.
[0008] Since the slit-like opening in the sleeve has to be kept as
narrow as possible, the awning canvas would brush along an edge of
the slit opening. If the slit opening were oriented, for example,
such that the awning canvas, when extended horizontally, could
extend out of the slit in a contact-free manner, the awning canvas
would brush along the bottom slit end in the case of it being
inclined. Furthermore, it would not be possible for the opening-out
rod at the opening-out end of the awning canvas to be advanced
right up to the slit opening.
[0009] Provision is thus made for the sleeve to be configured such
that it can be rotated about the awning-canvas-shaft axis, with the
result that the slit-like opening can be oriented in accordance
with the desired angle of inclination.
[0010] In the case of a known design, this adjustability is
achieved such that two diametrically opposite stay bolts project
axially laterally from the sleeve, it being possible for said stay
bolts to be displaced in corresponding circumferential slots in the
lateral holder which extends over a certain circumferential angle.
In the desired rotary position, the stay bolts are then secured by
clamping via lock nuts which can be screwed in the axial direction
from the outside. The adjusting angles here extend approximately up
to 55.degree..
[0011] The installation procedure is such that, once the awning has
been installed, these lock nuts are released and the sleeve is
rotated, in accordance with the customer's wishes, into the desired
extension inclination of the awning canvas, and the lock nuts are
then screwed tight again.
[0012] The disadvantage with this securing principle, is that, over
the long term, the sleeve can rotate relative to the holder. When
awnings are extended, gusts of wind subject them to considerable
forces which, despite the adjusting screws being firmly tightened,
may result in the inclination being adjusted. In particular, in the
case of very wide awnings which can be extended to a very great
extent, the extended awning-canvas surface provides a considerable
surface area on which such forces can act.
[0013] A further disadvantage is that all the components of an
awning are usually coated with materials which have a very smooth
surface. This is carried out not just for the sake of the visual
appearance, but also so that the awnings exposed to the
environmental influences do not gradually become soiled in an
unsightly manner as a result of dirt adhering to rough surfaces.
These smooth surfaces aid rotation of the sleeve when the awning is
blown upwards by gusts of wind.
[0014] If the customer changes his/her mind in respect of the
inclination setting, it is necessary, in order for it to be
possible to carry out the manipulations which are necessary in the
axial direction, to remove lateral end caps in order to gain access
correspondingly.
[0015] If the awning extends over the entire width of a balcony
projecting from a wall of a building, it is thus necessary to carry
out manipulations which involve reaching laterally beyond the
balcony, which constitutes a risk for the person carrying out the
manipulations and should thus not be carried out by the customer
himself/herself.
[0016] Approaches to the solution have been sought to the effect of
configuring the adjusting arrangement such that, as seen from the
radial direction, correspondingly directed manipulations are
possible for adjusting purposes.
[0017] It is then necessary, however, to provide corresponding
mechanisms which convert these manipulations into rotary movements
of the sleeve.
[0018] However, it is an aim for cassette awnings and sleeve
awnings to be designed to be as narrow as possible and with as
little bulk as possible, that is to say, to depart from the
large-volume box awnings and ultimately to provide a structure
which is determined essentially by the outer contour of the narrow
sleeve, or, in the case of cassette awnings, by the contour of the
cassette which additionally covers the arms, this usually being
carried out by the opening-out profile of the opening-out rod.
[0019] It is the object of the present invention to provide an
awning, with an arrangement for adjusting the inclination of the
sleeve, which allows straightforward and permanently remaining
adjustment of the inclination and is not bulky.
SUMMARY OF THE INVENTION
[0020] The object is achieved according to the invention in that
the arrangement has in each case one lateral sleeve carrier which
is connected to the respective lateral holder and can be rotated
relative to the holder about the awning-canvas-shaft axis, in that
the sleeve carrier contains a slot opening which extends in the
tangential direction in relation to an imaginary turning circle and
in which a sliding block runs, in that there is provided an
actuating element which can be moved rectilinearly in the direction
of the slot opening and is supported, on the one hand, on the
sleeve carrier and, on the other hand, on the sliding block, and in
that the sliding block, furthermore, extends in a further slot
opening, extending radially in relation to the awning-canvas-shaft
axis, in the stationary holder and is supported therein.
[0021] These measures, then, have a number of considerable
advantages.
[0022] An actuating element which moves tangentially in relation to
an imaginary turning circle can be actuated by an operator standing
in front of the awning; that is to say there is no longer any need
for manipulations extending laterally beyond the awning.
[0023] A sliding block which moves along a tangent is spaced apart,
depending on the displacement along the tangent, to a more or less
great extent from the center point of said imaginary turning
circle, that is to say is at a variable spacing from the axis of
rotation of the awning-canvas shaft. This radial movability, then,
is provided by the stationary holder containing corresponding
radially extending slot openings in which the sliding block is
supported.
[0024] This basic principle, then, makes it possible, by
rectilinear adjustment of the actuating element, to allow rotation
of the sleeve carrier relative to the stationary holder by the
sliding block being displaced rectilinearly along the slot opening
by the actuating element. This linear movement is converted into a
rotary movement of the sleeve in that the sliding block is
supported on the stationary holder. The necessary radial
movability, that is to say, the change in the radial spacing of the
sliding block from the axis of rotation is made possible, at the
same time, in that this opening is designed as a radial slot
opening in the stationary holder. The interaction of these basic
components provides an extremely compact adjusting arrangement
which is convenient to operate and does not detract from the outer
appearance of the narrow awning. At the same time, the actuating
element, which rests on the sliding block, blocks the sleeve
carrier against further inclination, with the result that even very
heavy awnings which extend to a great extent are reliably retained
in the inclined position.
[0025] In a further configuration of the invention, provision is
made for two mutually opposite arrangements of this type, with
their sliding blocks running in opposite directions, to be formed
in relation to the awning-canvas-shaft axis.
[0026] This measure, then, has the advantage that, in addition to
the inclination adjustment, it is also possible, at the same time,
using the same components, to inhibit the awning from blowing
upward.
[0027] The sliding block, which can be displaced in the tangential
slot opening, has the actuating element acting on it, and adjusting
it, from one side. This means that it could move away from the
actuating element in the opposite direction, for example, if, with
the awning canvas extended, the latter is forced upward. In other
words, the actuating element rests on the sliding block with
support in the direction of gravitational force.
[0028] Providing the second, approximately diametrically opposite
arrangement of the same design, then, makes it possible to achieve
an additional means for inhibiting the awning from blowing upward.
Since this arrangement is located diametrically opposite, its
actuating element, which can be adjusted rectilinearly from the
same side as the other actuating element, blocks the sliding block
of the second arrangement, this sliding block running in the
opposite direction to the first sliding block, in the direction
which is left free by the other actuating element.
[0029] In other words, one arrangement serves for adjusting the
inclination, while the actuating element of the other arrangement
blocks the awning from being blown upward in the opposite
direction.
[0030] Basically just one of these arrangements can adjust the
inclination; the other secures the awning against being blown
upward.
[0031] The two arrangements are nevertheless of substantially
identical design, but are arranged on two opposite sides of the
axis of rotation.
[0032] Opposite does not mean that these have to be located exactly
diametrically opposite one another, nor does it mean that the two
slot openings have to extend parallel; rather it is also possible
for the tangents to form the legs of a V.
[0033] In a further configuration of the invention, the actuating
element is designed as a screw which runs in a thread formed in the
sleeve carrier.
[0034] This measure has the advantage that a stable actuating
element which is easy to handle is provided by means of a screw.
The necessary opposing force in relation to the movable sliding
block is absorbed by the thread. These components can easily be
accommodated in the sleeve carrier since the latter is of
approximately the same dimensions, in any case, as the diameter of
the sleeve. This thread may be cut into the body of the sleeve
carrier, with the result that there is no need for any laterally
projecting structural means.
[0035] In a further configuration of the invention, the sliding
block has a securing arrangement via which the sleeve carrier and
the lateral holder can be clamped to one another.
[0036] This measure, then, has the advantage that, in the desired
inclined position of the sleeve, the position of the sliding block
is secured and thus, at the same time, the sleeve carrier and
lateral holder are clamped to one another.
[0037] This configuration may be selected both when just one
arrangement is provided, in which case this also acts as a means
for inhibiting the awning from blowing upward, and when the two
diametrically opposite guide means are provided, in which case,
this configuration serves as an additional securing
arrangement.
[0038] In a further configuration of the invention, the securing
arrangement has an adjusting screw which is accommodated in a
thread in the sliding block.
[0039] This measure has the advantage that the sliding block can be
secured by a structurally straightforward means.
[0040] In a further configuration of the invention, a head of the
adjusting screw and the sliding block each rest on shoulders in the
slots.
[0041] This measure has the advantage that, once again, by
particularly straightforward means which do not project to a great
extent, the captive mounting, the displaceability and also the
securability of the sliding block are made possible. Since
corresponding shoulders are cut into the slots both of the sleeve
carrier and of the holder, there is no need for any structural
means which project laterally beyond these components. These
shoulders constitute additional guides both for the screw and for
the sliding block. In order to allow the displaceability, all that
is required is for this screw to be released to some extent, the
screw then moving, together with the sliding block, during
displacement. Tightening the screw then brings about the additional
securing action and the clamping between the sleeve carrier and the
lateral holder.
[0042] In a further configuration of the invention, the sleeve
carrier bears an arm bearing for an awning arm.
[0043] This measure, then, has the considerable advantage that the
awning arm can thus extend in the respective plane of inclination
of the sleeve since its inclination is automatically adjusted along
therewith. This results in a particularly compact and narrow
cassette awning.
[0044] In a further configuration of the invention, the lateral
sleeve carrier and the lateral holder butt against one another via
in each case one plate-like section, it being possible for these
sections to be rotated relative to one another about the
awning-canvas-shaft axis.
[0045] This measure has the advantage that the plate-like sections
provide stable basic bodies which butt against one another over a
relatively large surface-area section but can slide past one
another with the result that it is possible to absorb laterally
acting tilting forces as a result of the awning-canvas shaft being
bent on account of the gravitational force or on account of the
forces during the extending operation. As a result of the
large-surface-area abutment, even relatively low clamping forces
are sufficient in order to avoid these two elements rotating
relative to one another as a result of gusts of wind when the
awning is extended.
[0046] In a further configuration of the invention, the plate-like
sections each have a central opening for accommodating a journal of
the awning-canvas shaft.
[0047] This measure has the advantage that not just a centering
action, but also the absorption of forces which are exerted by the
awning-canvas-shaft journal can be distributed uniformly over the
two elements.
[0048] In a further configuration of the invention, projecting from
one of the plate-like sections is a neck which is accommodated in
the other plate-like section.
[0049] This measure has the advantage not just that
straightforward, centered installation is made possible, as a
result of these two plate-like sections being plugged one inside
the other, but also that the neck allows a correspondingly guided
rotary movement during the inclination adjustment.
[0050] In a further configuration of the invention, the holder
contains a plurality of radially oriented slot openings which are
offset through approximately 90.degree. in relation to one another
in the circumferential direction.
[0051] This measure has the considerable advantage that one and the
same holder can be used for installation both on a vertically
upright wall and in the hanging state on a ceiling.
[0052] It goes without saying that the features which have been
mentioned above and those which have yet to be explained
hereinbelow can be used not just in a combination specified, but
also in other combinations or alone, without departing from the
scope of the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0053] The invention is explained and described in more detail
hereinbelow, with reference to a selected exemplary embodiment in
conjunction with the attached drawings, in which:
[0054] FIG. 1 shows a perspective view of a left-hand outer end of
an awning as seen from inside,
[0055] FIG. 2 shows a corresponding perspective view of this holder
as seen from the left-hand outer end side, the sleeve and the
awning-canvas shaft also being schematically indicated here in
addition,
[0056] FIG. 3 shows a view, corresponding to FIG. 1, in a position
which is inclined downward through approximately 30.degree.,
[0057] FIG. 4 shows an illustration, corresponding to FIG. 2, with
an inclination through 30.degree. in the downward direction,
[0058] FIG. 5 shows an illustration, corresponding to the
illustration of FIG. 1, in an inclined position of approximately
60.degree. in the downward direction, and
[0059] FIG. 6 shows a view, corresponding to FIG. 2, of the
position which is inclined downward through 60.degree..
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0060] FIGS. 1 and 2 illustrate the left-hand outer end of an
awning which is designated 10 overall.
[0061] The corresponding right-hand outer end (which is not
illustrated here) is of mirror-inverted design.
[0062] As can be seen schematically from FIG. 2 in particular, the
awning 10 has a sleeve 12 which encloses an awning-canvas shaft 14
on which an awning canvas 16 has been wound up.
[0063] The awning canvas 16 is guided out of the sleeve 12, and
retracted into the latter again, through a slit-like opening
18.
[0064] For this purpose, as is known per se and need not be
described any more specifically here, the opening-out end of the
awning canvas 16 is provided with a corresponding opening-out rod,
which ends up located in front of the slit-like opening 18 and via
which the awning canvas 16 is drawn out. The opening-out rod is
then connected to a corresponding mechanism, for example to a
hinged arm which is known per se, which achieves the opening-out
movement in conjunction with a drive mechanism.
[0065] The operations of retracting said awning canvas 16 and
winding it up onto the awning-canvas shaft 14 are achieved in that
the awning-canvas shaft 14 is rotated about the awning-canvas-shaft
axis 36, that is to say, in the exemplary embodiment illustrated
and in the view of FIG. 2, by rotation of the awning-canvas shaft
14 in the counterclockwise direction.
[0066] These mechanisms are sufficiently known to the person
skilled in the art and thus need not be described in any more
detail.
[0067] The awning 10 also has a support means 20.
[0068] This support means 20, as can be seen from FIG. 2 in
particular, has a lateral holder 22 which, via two claws 24 and 26
projecting from it, is firmly connected to a retaining rail 28.
[0069] In the exemplary embodiment illustrated, the retaining rail
28 is fastened on a vertical wall 30, for example, the outside of a
building, above a balcony which is to be provided with shade.
[0070] The lateral holder 22 has a plate-like section 32 which has
a central opening 34 of which the center point is located along the
awning-canvas-shaft axis 36.
[0071] In this embodiment, four radial slot openings 38, 39, 40 and
41 are provided in the plate-like section 32. The four radial slot
openings 38 to 41 are offset, in this embodiment, through
90.degree. in relation to one another in each case in the
circumferential direction.
[0072] From the inside of each radial slot opening 38, 39, 40 and
41, a shoulder projects inward from the outside, that is to say as
seen in the viewing direction of FIG. 2, only the shoulder 42 of
the radial slot opening 38 being designated in this figure, but the
other slot openings being provided with similar shoulders.
[0073] The support means 20 is assembled in a stationary, rigid and
stable manner with the retaining rail 28.
[0074] A sleeve carrier 50 is arranged on the inside of the holder
22, as can also be seen, in particular, from FIG. 1.
[0075] The sleeve carrier 50 has a plate-like section 52 which is
of approximately circular contour and, in the opening-out direction
of the awning canvas, has a nose 54 which bears an arm bearing
56.
[0076] Illustrated in the arm bearing 56 is a pin 58, via which an
arm, for example a hinged arm, can be fastened on the arm bearing
56. The arm (which is not illustrated here) can thus be pivoted
about the longitudinal axis of the pin 58.
[0077] In the case of a hinged-arm-awning design, the outer
opening-out end of the bottom arm of the hinged arm is connected to
the abovementioned opening-out rod, which is fitted at the outer
opening-out end of the awning canvas 16.
[0078] Provided in the plate-like section 52 of the sleeve carrier
50 is a central opening 60, which is encircled by a projecting neck
62 from the side which is directed toward the holder 22.
[0079] In the installed state, this neck 62 is fitted into the
central opening 34 of the holder 22, as can be seen from FIG. 2 in
particular. In this state, the outer circumferential side of the
neck 62 butts in a closely fitting manner against the inner
circumferential side of the central opening 34, with the result
that the two plate-like sections 32 and 52 are centered about the
central awning-canvas shaft axis or axis of rotation 36.
[0080] The plate-like section 52 of the sleeve carrier 50 is
generally planar and, in this case, butts over the surface area
against the corresponding inner side of the plate-like section 32
of the holder 22, as can likewise be seen from FIG. 2.
[0081] Provided in the inside of the neck 62 are two diametrically
opposite axial grooves 64 and 65 which serve for accommodating, in
a closely fitting manner, a correspondingly shaped laterally
projecting journal (not illustrated here) of the awning-canvas
shaft 14. The parts which butt against one another over their
surface areas are located in a rotary plane 66. Also provided on
the inside of the sleeve carrier 50 are drain openings 68, which
allow any condensation which may have collected to flow out of the
sleeve 12.
[0082] The sleeve 12, then, is installed on the inside of the
sleeve carrier 50 such that it has its end-side annular surface
located on the plate-like section 52 and it terminates the latter
in an approximately flush manner in the circumferential direction,
as can be seen from FIG. 2. Corresponding openings and screws serve
for fastening the sleeve 12 in a predetermined position on the
inside of the sleeve carrier 50.
[0083] As can be seen from FIG. 1 in particular, the sleeve carrier
50 contains an approximately tangential slot opening 70 which runs
tangentially to an imaginary turning circle 71, which is indicated
by dashed lines in FIG. 1.
[0084] As seen from the inside of the sleeve carrier 50, that is to
say in the viewing direction of FIG. 1, a circumferentially running
shoulder 72 projects inward from the inside of the slot opening
70.
[0085] A sliding block 74 rests on this shoulder 42 and in the slot
opening 70.
[0086] The sliding block 74 is designed such that it can move back
and forth along the tangential slot opening 70 but, on account of
the shoulder 42, cannot pass axially from the inside to the outside
through the slot opening 70.
[0087] An adjusting screw 76 is accommodated in sliding block 74,
and its head 78 can be seen from FIG. 2.
[0088] The head 78 of the adjusting screw 76 here is accommodated
in the radial slot opening 39 of the holder 22 and the underside of
the head 78 rests on the corresponding shoulder 42 in this slot
opening 39.
[0089] The adjusting screw 76 can be screwed into the sliding block
74 and unscrewed therefrom, in the axial direction, that is to say
generally parallel to the awning-canvas-shaft axis 36.
[0090] This assembly in conjunction with the shoulders in the
openings forms a securing arrangement 80.
[0091] This is because, if the adjusting screw 76 is screwed tight,
the two plate-like sections 32 and 52 are drawn axially against one
another and clamped to one another.
[0092] Provided for the purpose of displacing the sliding block 74
along the tangential slot opening 70 is an actuating element 82,
which is designed as a screw 84 which runs in a thread 86 cut in
the plate-like section 52 (see FIG. 2).
[0093] A corresponding fillet groove 88 is cut, from the outside,
in the plate-like section 52, in particular in the region of the
nose 54 thereof, and the actuating element 86 rests therein.
[0094] The end side of the screw 54 thus rests on that side of the
approximately cuboidal sliding block 74 which is directed toward
it.
[0095] As can be seen from FIGS. 1 and 2, a second tangential slot
opening 90 is provided, this being located approximately
diametrically opposite the first tangential slot opening 70, but
being otherwise of the same design. That is to say, this slot
opening 90 also has a shoulder 92, on which a sliding block 94
rests. This sliding block 94 is also provided with an adjusting
screw 96, of which the head 98 is accommodated in the radial slot
opening 41, as can be seen from FIG. 2 in particular. Here too, a
securing arrangement 100 is provided by the interaction of the
sliding block 94, the head 98 of the adjusting screw 96 and the
shoulders 92 and 42.
[0096] The second tangential slot opening 90 is assigned an
actuating element 102 in the form of a screw 104, which runs in a
thread 106 cut in the body of the plate-like section 52. Here, too,
a corresponding fillet groove 108 is provided on the outside of the
sleeve carrier 50, and the screw 104 is accommodated therein.
[0097] The components in conjunction with the second tangential
slot opening 90 constitute, overall, an arrangement 110 for
adjusting the inclination of the sleeve 12.
[0098] The principle of the inclination adjustment will be
described taking the relative position between the holder 22 and
sleeve carrier 50 as is illustrated in FIGS. 1 and 2 as the
departure point.
[0099] The relative position illustrated in FIGS. 1 and 2 is the
angle of inclination 0.degree., that is to say the awning canvas 16
is extended approximately horizontally.
[0100] The sliding block 94 in the second tangential slot opening
90 is located in its extreme right-hand displacement position in
the illustration of FIG. 1, and the screw 104 has been screwed in
to the maximum extent and is supported on the sliding block 94.
[0101] The tilting moment of the arm accommodated by the arm
bearing 56 forces the screw 104 onto the sliding block 94.
[0102] If the screw 104 is then unscrewed, the sleeve carrier 50
rotates in the counterclockwise direction, in the view of FIG. 1,
about the awning-canvas-shaft axis 36, and the nose 54 is thus
inclined downward.
[0103] In relative terms, the sliding block 94 slides to the left
along the second tangential slot opening 90, as can be seen from
the change between FIGS. 1 and 3.
[0104] At the same time, the sliding block 74 has been displaced
correspondingly to the right from the extreme left-hand position in
the slot opening 70, seen in FIG. 1.
[0105] In FIG. 3 and correspondingly in FIG. 4, the screw 84 is
illustrated in the already adjusted state, but it is also possible
for this to take place for the first time at a later point in
time.
[0106] It can be seen from the change between FIGS. 1 and 3 that
the radial spacing of the sliding block 94 from the axis of
rotation 36 has changed to the effect that the radial spacing is
smaller in the position of FIG. 3. In this case, the sliding block
has advanced approximately tangentially toward the imaginary
turning circle 71. The path difference or the radial relative
movement is made possible in that the sliding block 94 has moved in
the radial direction along the radial slot opening 41, as can be
seen by the change in position between FIGS. 2 and 4. It has thus
been able to move radially inward along this slot opening 41.
[0107] If the screw 104 is unscrewed yet further, then the sleeve
carrier 50 is inclined yet further, as can be seen from the change
between FIGS. 3 and 5, which corresponds to a change between an
angle of inclination of approximately 30.degree. and an angle of
inclination of approximately 60.degree..
[0108] It can be seen from FIG. 5 that the radial spacing of the
sliding block 94 from the awning-canvas-shaft axis 36 has increased
again; accordingly, the head 98 of the adjusting screw 96 of the
sliding block 94 has moved radially outward again in the change
between FIGS. 4 and 6.
[0109] FIGS. 5 and 6 illustrate the maximum inclined position of
the sleeve carrier 50, and thus of the sleeve 12, which, in the
exemplary embodiment illustrated, is approximately 60.degree. from
the horizontal. It is also possible, however, to achieve an angle
of inclination of up to 90.degree. using a correspondingly longer
design.
[0110] It can be seen from the illustration of FIG. 5 that the
sliding block 94 has now arrived at the left-hand end of the slot
opening 90.
[0111] If the inclination is to remain in this position, the screw
84 is screwed in until it butts against the sliding block 94. This
inhibits the awning from blowing upward. In the case of the latter,
which should correspond to a change between FIGS. 3 and 1, it would
be necessary for the sliding block 74 to be able to move to the
left in relative terms in the slot opening 70. This is blocked when
the screw 84 has been screwed into the extent where it butts
against the sliding block 74.
[0112] The respective adjusting screws 76 and 96 are then
tightened.
[0113] If the inclination is to be reduced again from the position
set in FIG. 5 or 6, the adjusting screws 76 and 96 are
correspondingly released, the screw 104 is correspondingly screwed
in, and the screw 84 is unscrewed.
[0114] In the exemplary embodiment illustrated, the awning 10 is
installed such that the retaining rail 28 is installed on a
vertical wall 30.
[0115] If the retaining rail 28 is installed on a ceiling, the
awning canvas would then extend vertically from the position
illustrated in FIGS. 1 and 2 and could then be "inclined" inward if
need be.
[0116] If a corresponding inclination in the outward direction from
the vertical should then be desired, the sleeve carrier 50 is
fitted on the holder 22 in a manner offset through 90.degree., that
is to say, rather than being inserted into the radial slot openings
39 and 41 as is shown, for example, in FIG. 2, it is inserted into
the slot openings 38 and 40 which are offset through 90.degree. in
relation thereto.
